This work was motivated by the need for perceptualizing nano-scale scientific data, e.g., those acquired by a scanning probe microscope, where collocated topography and stiffness distribution of a surface can be measured. Previous research showed that when the topography of a surface with spatially varying stiffness is rendered using the conventional penalty-based haptic rendering method, the topography...
This work has been motivated by our prior efforts for perceptualizing the scientific data sets of surface topography and stiffness distribution measured with a scanning probe microscope. Previously, we showed that the surface topography information with varying stiffness rendered with the conventional penalty-based method can be distorted (Choi et al., 2005), and developed a topography compensation...
